A mom and her four children were among the seven people who were killed Sunday morning after a wrong-way driver caused a head-on collision in Northern Illinois.

Lauren Dobosz, 31, was going on vacation in Minnesota with her husband, 32-year-old Thomas Dobosz, and her four children — who ranged in age from 5 to 13 — when their vehicle was hit, friends and family said, according to the Chicago Sun-Times and WLS-TV. Joining the family on the trip was a 13-year-old family friend, who also died, the outlets reported.

Both vehicles were “fully engulfed” in flames after the crash took place around 2 a.m. local time on Interstate 90 in McHenry County, Illinois State Police said in a statement. The driver of the first car, Jennifer Fernandez, a 22-year-old from Carpentersville, died at the scene.

Lauren’s husband, who was driving their vehicle at the time, is the sole survivor and remains hospitalized, according to NBC Chicago.

An investigation into the cause of the crash is open and ongoing, Illinois State Police told PEOPLE when reached for comment on Tuesday.
